• 🟡 (09:22) Review inspection continued into the SessionExecution implementation that imports LocationServiceMap, SessionStore, and SESSION_EXECUTION_LEASE_MS; it documents current-process routing for implicit-local Locations and reserves future remote placement for that layer.
• 🟡 (09:22) The inspected implementation computes leaseDuration with Duration.toMillis(SESSION_EXECUTION_LEASE_MS), tracks process-local claims in activeClaims, and tracks shared interrupt cleanup work in interruptions.
• 🟡 (09:22) Claim execution uses { sessionID, executionID, ownerID }, races execution against lease/ownership handling with Effect.raceFirst(...), and removes activeClaims[sessionID] only when its stored executionID still matches.
• 🟡 (09:22) Post-execution interruption handling reloads the exact SessionExecutionTable row using the claim’s session/execution/owner identity; when Cause.hasInterrupts(exit.cause) and the current phase is not "safe", it returns without ordinary cleanup.
• 🟡 (09:22) Recovery logic clears an exact claim immediately when its phase is "cancelled".
• 🟡 (09:22) Recovery inspects the assistant message and filters unresolved tool parts. If an assistant message is already completed but unresolved tools remain, it publishes durable unknown-tool outcomes with error { type: "unknown", message: "Tool execution interrupted" }.
• 🟡 (09:22) Cancellation settlement joins durable tool-outcome publication and interruption finalization transactionally, including SessionExecutionClaim.settleCancellation(db, claim, { phase: "cancelled", assistant_message_id: null }).
• 🟡 (09:22) SessionExecution.interrupt first checks activeClaims.get(sessionID), shares concurrent cleanup through the interruptions map, uses Effect.raceFirst(...) while waiting, and deletes an interruption entry only if the map still contains that exact interruption instance.
• 🟡 (09:22) The inspected service exposes resume: coordinator.run; its layer supplies a run implementation via Effect.fnUntraced(function* (claim, force, recoveryInputID) { ... }).
